Hi Frank,

how should we proceed with this? You provided your Reviewed-by months ago, but
the patch never got applied. It is also marked as 'archived' in patchwork:
https://patchwork.kernel.org/project/linux-arm-kernel/patch/20260224152523.570057-1-nora.schiffer@ew.tq-group.com/


I'm not sure if changing the aliases at this point would be too much of a
breaking change... would it make sense to resubmit it, or should I consider it
rejected?

Best,
Nora
